If you do grab Sprawl Wilds, my guess is Humanitarian Aid is out of a starting league. The other three likely work fine.
I'm guessing Humanitarian Aid is the name of the 4th mission. The first 3 worked well with a starting party. (Haven't played the 4th.)
However, I will state that for starting characters, they will be outclassed in the combats, so proper planning is very necessary. The enemies will have the numbers, bigger guns, and are faster and aim better. We used drones as a crutch in mission 1 and 2 from Sprawl Wilds (losing a bunch of drones in the process.) Not sure how those combats would have gone otherwise. We didn't have drones in mission 3, and although that was probably the easiest fight by design, it was by far the hardest for us due to not having as many guns around laying down suppressive fire.
